The antioxidant metabolome as a part of metabolome of  mbryophytes presents the total low molecular weight hydrophylic and hydrophobic metabolites with antioxidant activity which take part in protection and regulatory plant reactions. The main function of antioxidant metabolites is deactivation of active forms of oxygen and free radicals appearing ue to biotic and abiotic stresses. The level of resistance to oxidative stress of each plant is defined by total metabolome of antioxidants (content, speed of synthesis, accumulation, utilization) depending on genotype, but can be changed under the action of environment.

Using the high-efficiency liquid chromatography, the phenolic compounds of yacon (Polymnia sonchifolia) introduced in Ukraine have been studied. The derivants of hydroxycinnamic acid is prevalent in the ethanol extracts from leaves and roots of yacon. Differences in the contents of  ethanol extracts from fresh and dry roots were shown. The total amount of hydroxycinnamic acids was 2,8 % – 4,3 % depending on the layer of leaves. It was found that roots content 36-45% of fructosans expressed as fructose and dry matter.

There is collaboration between VNIISSOK and Mongolian Ministry of Agriculture in field of vegetable growing and seed production supported by the Swiss Agency of development and cooperation (SDC). Based on the preliminary results of variety trials, Mongolian researchers and breeders have found the promising cultivars of vegetable crops of VNIISSOK breeding suitable for growing in condition of Mongolia.

Application of such biotechnological method as a callus culture, allowed developing the somaclonal variants of cucumber, six of which were selected as a regenerated lines for the breeding program. New forms are characterized by early-ripeness, percent of parthenocarpy, good quality, yield and fruit weight. These lines can be used as an initial material for heterosis breeding and for improvement of donor cultivars of cucumber.

The success in the development of the Institute is associated with seed production and marketing of vegetable varieties of VNIISSOK’s breeding. The affiliated organization, the North-Caucasian experimental station is a structural subdivision of the All- Russian research institute of vegetable breeding and seed production. The stuff of this experimental station work on the problem of seed production of onion, root, cucurbitaceae and leguminous crops in condition of the North-Caucasus.

Data of presented varieties and distribution of estragon crop are described. Morphological characteristics, biochemical composition, health giving qualities, and nutrition value are presented. The problems of seed multiplication, growing, yield, and harvest of this crop are discussed.

The data of spring-summer sowing time of vegetable root crops of the family Brassicaceae in the open filed are presented. Five varieties and three hybrids of daikon, seven varieties of radish, and four varieties of turnip were tested. Based on the results, the minimal and maximal root weight for each time of sowing were determined; average fresh weight of vegetable roots for three years of investigation was accounted.

The results of study of influence of climatic conditions associated with vertical zonality on the defeat and spread of viral diseases, as well as on the yield of potato are presented. The use of favorable natural and climatic conditions of the mountainous province of the Dagestan Republic for establishment of production virus-free potato seeds allows to increase the potato production in Republic.

The results of evaluation of the collection of sweet corn hybrids Bonus, Spirit, NOA, and Trophy for for earliness and yield are presented. The hybrids NOA and Bonuses are recommended for growing of sweet corn in the agro-climatic conditions of southern agricultural zone of the Amur Region.

In 2013, the new vegetable pea cv.Prima was applied for the State Variety Trial. This variety is characterized by very yearly-ripeness, that allows to increase the raw material processing in the canning factories of the Kuban.
